Substation automation encompasses a combination of hardware and software components designed to monitor and manage an electrical system's operations, both at the local and remote levels. The primary objective of substation automation is to improve the functionality and maintenance of crucial power grid substations responsible for transforming, distributing, and regulating electrical energy.

The key elements of substation automation include hardware and software. Hardware refers to both external and internal devices and equipment that facilitate essential operations such as input, output, storage, communication, and processing. In the context of substation automation, hardware is utilized to oversee and control the electrical equipment within substations. Substation automation is applicable across various voltage levels, including low voltage, medium voltage, and high voltage, utilizing communication channels such as optical fiber, power line, copper wire, Ethernet, and others. The modules it incorporates include SCADA (supervisory control and data acquisition), IED (intelligent electronic devices), communication networks, and other modules catering to the needs of industries such as utilities, steel, oil and gas, mining, and transportation.

The substation automation market consists of revenues earned by entities by providing substation automation services such as planning, designing, and engineering of substation automation systems, and testing and maintenance of systems. The market value includes the value of related goods sold by the service provider or included within the service offering. The substation automation market also includes sales of Remote Terminal Units (RTUs), Programmable Logic Controllers (PLCs), Human Machine Interfaces (HMIs) and Power Quality Monitoring devices.
